Standards track RFC 4343 was issued within the past five years (January 2006 to be precise). It contains some example domain names that do not follow the suggestions in RFC 2606 as well as some that do. As the author of both RFC 2606 and RFC 4343, I believe the domain names reserved in RFC 2606 were intended to be encouraged but not mandatory.
